You've got the worst nature for Blaziken, Marshadow and Ash Greninja.

If you really want to do a competitive team, I suggest you rework your team and find best natures and focus on useful IVs and EVs.

Grass + Fire + Water core is fantastic, but Blaziken must be Speed Boost to use, or simply mega. I would replace serperior with Venusaur which offers better offensive / defensive utility. Ash Greninja unfortunately has poor nature, so rework new one. Or replace with Primarina.

Add Ferrothorn with egg moves (replace marshadow) in order to complete Fairy + Dragon + Steel core. (Primarina, Salamence, Ferrothorn).

Salamence should have an egg move, Dragon Dance. Dragon Dance and D-Edge or Return are a must for Mega Salamence.
